Sad sign of the times in Issues & Politics Posted February 17, 2018 1 hour ago, Hawkwin said: "Absence of evidence is not evidence of absence." It also doesn't say there isn't a relationship between those that are born with two eyes and those that commit crimes but I bet the correlation is higher than those that use drugs and commit crimes. Because the study doesn't say it doesn't exist, we might want to start poking out everyone's extra eye based on that absence of evidence. We can clearly infer that there is a correlation between having two eyes and crimes. Good thing correlation isn't the same thing as causation. Right. So the data is not definitive either way so both your argument and his is not proven by the data.
